[PATCH 13/17] virDomainTPMDefParseXML: Switch to virXMLPropEnumDefault()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The virDomainTPMDefParseXML() function uses old style of parsing
XML (virXMLPropString + str2enum conversion). Use
virXMLPropEnumDefault() which encapsulates those steps.
